SPOKE SHAVE Filed Aug. 17, 1928 IN VEN TOR.

A TTORNEYJ Patented Dec. 3, 1929 UNlTED STATES FREDERICK L. MAYER, OF MILWAUKEE, WISCONSIN SPOKE SI-IAVE Application led August 17, 1928. Serial No. 300,232.

This invention relates to improvements in spoke shaves.

Spoke shaves, aslieretofore used by Wood- Workers and pattern makers, have consisted of a Wooden body portion, and a cutting blade with inwardly projecting' and right- Asingularly bent end portions insertable in holes in said body. rllhe ends fitted tightly in the receiving1 holes and said ends projected through the other side of the body.

No means was provided for adjusting the blade. lvVhen this Was necessary, the user would hammer upon the projecting` ends to force the blade out a desired distance. Not only was the method of adjustment troublesome, but it Was unsatisfactory, as the pressure upon the blade, When using the device, would soon force it to a non-cutting position, as no means was provided for preventing movement of the projecting ends of the blade Within their receiving; holes. Furthermore,

the blade would frequently grip the Wood and be pulled out a greater distance than would be desired.

lt is one of the objects of this invention to overcome the above-mentioned objections by providing` an improved spoke-shave having an adjustable cutting blade, and having means for rigidly maintaining said blade in any desired cutting,1 position. j

lt a more specific object of this invention to provide an improved spoke shave in which the inwardly projecting' ends of the cutting blade have roughened surfaces adapted to be engaged by the ends of adjustment bolts, which are threaded in the body portion, to hold the cutting blade rigidly in any desired position.

lt is a further object of this invention to provide an improved spoke shave Which is simple in construction, inexpensive to manufacture, and well adapted for the purpose described.

.r TWith the above and other objects in View, the invention consists of the improved spoke shave, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.

ln the accompanyinp,` drawings, in which the same reference characters designate the saine parts in all of the views:

Fig. 1 is a plan vieuT of the device;

Fig. 2 is a bottom View thereof;

F 3 is a sectional View talien on line 3--3 of Fig. 2;

Fig'. 4 is a sectional view. taken on line l--li of Fig. 3,

Fig. 5 is a sectional View taken on line .li-5 of Fig. 8; and

Fig. 6 is a perspective view of the cutting; blade removed from the body portion.

Referring to the drawing, the numeral 8 designates the body portion generally, the said body portion being` formed with an enlarged central portion 9, having a blade recess 10 therein, and with narrowed or rounded end portions 11, which are adapted to be gripped by the user. On each side of the recess 10 are square openings 12 extending transversely through the body portion. Recesses 13 extend from the sides of the recess 10 to the lower ends of the openings 19..

The cutting member comprises a blade 1li, having projecting` portions 15 which extend outwardly at each side of the blade for a short distance and th en at right angles thereto. The outer face of each of the projections `is roughened as at 16, and the inner face of each projection is also roughened as at 17. This roughening is preferably accomplished by cutting ridgescrossivise in the metal as shown. The blade is positioned in the body by inserting,1 the projections 15 in the openings 12, the said projections being readily movable therein `when not held by the adjustment means.

Each of the ends 11 of the body is provided With a bore 18 extending longitudinally `and communicating with the opening- 12, for

receiving a bolt 19 having` a knurled head 20. Rectangular recesses 21 extend from one side of the body to the bores 18. Nut-s 22 are positioned Within the recesses 21, the threaded opening of each nut being in alignment with its respective bore 18, so that the bolts 19 may be threaded therethrough.

In using the device, when it is desired 'to vary the adjustment of the cutting; blade, the bolts 19 are loosened by turning the lmurled heads 20, This causes the ends of the bolts to disengage the projections 15 of the blade so as toV permit said blade to be moved in or out as desired. When the blade has been properly positioned, the bolts are threaded inwardly until their inner ends engage the roughened outer sides of the blade projections to hold the blade rigidly in place. By having vthe outer sides of the blade projections roughen ed, a iirm engagement of the bolts with seid projections is assured, and the possibility of the blade projections slipping Within the openings 12 is practically eliminated. By further having the inner sides of the blade projections roughened, there is a frictional engagement between said sides and the sides vol the openings Which provides additional means for preventing the blade Vfrom moving. l

From the foregoing description it may be seen vthat the improved spoke shave is simple in construction and is Well adapted for the purpose described.

What I claim is:

Vl. A shaving tool comprising a body portion having a central recess, having transversely extending openings on each side of said recess, and having bores extending longitudinally from the endsy of the body portion to the transversely extending openings; a cutting blade having projecting end portions bent at right angles to said blade, said blade being positioned Within the central recess oi' the body, and said pro-jecting end portions being received by the transverselyV extending openings of said body; and bolts threaded in the' longitudinally extending bores and engaging the projecting ends of the blade for adjustably securing said blade in any desired cutting position.

2. A shaving tool comprisinfr a body portion having a central recess, Iiaving transversely extending openings on each side 0f said recess, and having bores extending longitudinally from the ends of the body portion to the transversely extending openings; a cutting blade having projecting end portions bent at right angles to said blade, said projectingend portions having roughened sides, said blade being positioned Within the central recess of the body, and said projecting end portions being received by the transversely extending openings of said body; and bolts threaded in the longitudinally extending bores and engaging the roughened sides of the projecting ends of the blade for adjustably securing said blade in any desired cutting position.

3. A shaving tool comprising a body portion having a central recess, having transverselyextending openings on each side of said recess, having bores extending longitudinally from the ends-of the body portion to the transversely extending openings, and having nut receiving recesses extending from one side of the-body portion to said longitudinally extion.

ll. A shaving tool comprising a body portion having a central recess, having transversely extending openings on each side of said recess, having bores extending longitudinally from the ends of the body portion to the transversely extending openings, and having nut receiving recesses extending from one side ofthe body portion to said longitudinally extending bores; a cutting blade having projecting end portions bent at right angles to said blade, said projecting end portions having roughened sides, one roughened side of each projecting end frictionally engaging a side of the opening, said blade being positioned Within the central recess of the body, and said projecting end portions being received by the transversely extending openings of said body; nuts Within the nut receiving recesses, their threaded openings being in alinement with the respective longitudinal bores; and bolts extending throufrh .the longitudinal bores and threaded in t 1e nuts and engaging a roughened side of the projecting ends of the blade for adjustably securing said blade in any desired cutting position.

In testimony whereof, I aliix my signature.
